answers and a better understanding let's turn to cornell university's larry brown, a ye owe physics professor chair of the earth and atmospheric department. dr. brown, thanks so much for joining us. is man to blame or is nature? what's your cake on this in. >> both, probably. i think we have the three suspects that you mentioned. a possible natural up tick, although that's a little bit unusual, quite unusual. suspects in the man-made category, include both hydro fracturing and the wais wastewater disposal. most suggest that hydro fracturing is not the cause, but it's been known for a long time pumping large amounts of water can trigger earthquakes. >> i know this is a complicated issue and not everybody out there is a gio physics professor, so could you explain for us how does pudge thing water in to the ground create an earthquake? >> several ways but the primary is the water weeks in the fault zones and weakens the strength that is the rocks and act as an effective lubricant so the faults which are held together by friction suddenly get greased and lip urged forces there already.
